Abstract

We optimize a novel W\WO3\Al2O3\Cu CBRAM cell allowing excellent control of Hour-Glass (HG) shaped Conductive Filament (CF), improving switching variability, disturb and retention at low current. We evidence for the first time the critical impact of the Cu chemical potential close to the HG constriction on state retention.
